Identities enable us to simplify complicated expressions. They are the basic tools chuukese song trigonometry used in solving trigonometric equations, just as factoring, finding common denominators, and using special formulas trigonometry verifying identities calculator the basic tools of solving algebraic equations. In fact, we use algebraic techniques constantly to simplify trigonometric expressions. Basic properties and formulas of algebra, such as the difference of squares formula and the perfect squares formula, will simplify the work involved with trigonometric expressions and equations.
